The Drift Muscle series came about in Japan after a falling out within D1GP. A 10 minute preview video/commercial of the series final shows some content from the Muscle Class and the Ladys Class. Yes, they do spell it Ladys class and we know the proper spelling is Ladies but that is what Drift Muscle calls the series. Plug in and watch some familiar faces competing in the Drift Muscle series which lacks the big media/impact of the D1GP days of old. It still looks like the competition is quite entertaining at least.
